Ubuntu :: How To Set Audio & Video
Jul 19, 2010
I have a Dell Inspiron 1525, X-UB 8.04. Audio: I want to be able to turn the volume up or down, I cannot find any control that does this. Video brightness: this has 2 settings in BIOS, (a) on battery (b) on
AC power. From time to time something (I have no idea what) turns the (b) setting down from 8 to 2 and the screen becomes very murky. The only way I know to fix this is to shut down & restart & go into the BIOS & turn it back up. Is there a way to reset (b) without having to shut down & restart? Is there a way to discover what bit of S-ware is the culprit?

I have a video file in which the audio runs faster than the video, so they quickly go out of sync. The way to fix it would be to separate the audio and video streams, speed up the video (the audio is FINE, it's the video that's wrong), and then recombining them. What is the easiest way for doing that?

Is there an application that anyone knows about that I can use to convert either an .flv or .ogg file that contains both audio and video to just an audio .ogg file (preferably vorbis+theora) without audacity? I'm fairly certain audacity could accomplish this but it seems like overkill for what I'm trying to do and the computer I'm trying to use does not run it so well.
::EDIT:: I should also mention that I've tried looking on google. I did find downloadhelper extension for firefox which uses ffmpeg to convert the files but I don't see any obvious way to strip the video.

Setting up a linux based church server to be placed with a collocation host.
-- Server will be used for:
--- providing .pdf files
--- live streaming of church services (audio for now audio video soon)
--- providing audio files
--- providing audio-video files
--- our internet web site
A. Is there a preferred Linux distribution that will make this easier?
B. What is the best format for audio and video files that will be viewed variously on Linux, Mac, and Microsoft operating systems? Files will need to be played on older versions of operating systems and may need a free or very low cost software to play (e.g. play on Win2k)
C. What software is best for recording the audio or audio-video files? Some additional funding might be justified for this software, particularly if it can also support live streaming.
D. What software is best for live streaming both on the file creation and the listening-viewing sides of the process?
Ideally we would like to have a single software suite to live stream, and make downloadable audio or audio-video files for later download, and not require those listening and viewing to have to install additional software. Keeping file sizes small is also desirable because some of our users will probably only have dial-up internet.

To get multimedia working, or explain what I'm doing wrong.
The problem is that none of the video players doesn't play video, they show only black window and play audio.
I have Fedora 11 Leonidas, fully up-to-date.
I have installed rpmfusion and livna repository.
I have installed following packages:
When I try to play video with totem, it doesn't output any error, but just doesn't play video.
with mplayer:
xine and kaffeine just say:
vlc:
I tried several different files, which works perfectly in windows and ubuntu.
I installed windows binary codecs for mplayer to /usr/lib/codec/

when i had windows xp i used to convert almost any videos video into audio (the whole video into audio) by going to [url], downloading vdownloader and just inserting the url in the box provided; waiting for a couple of minutes and having an mp3 format file at the location that i want it to be in the desktop. when i searched for something similar for linux, because vdownloader was an .exe file and obviously wasn't going to work on ubuntu.
i found that i could get a video downloaded from videos but not an audio - i wait for the video to finish buffering; click on places; computer; file system; tmp; then rename the video folder and copy/relocate it to where ever on the desktop. ending with this video format "flash video (video/x-flv)". my question is: is there a linux program where i get to convert the entire video format to an audio format, possibly mp3?

Is there a video editor that also allows me to edit the audio. For example I have 2 videos and want to take the audio from one clip and add it to the other clip. I have tried Avidemux and Pitivi but these don't seem to have this ability.

I've recorded some video in the field, i.e. outside, windy, noisy, etc. I would like to strip out the audio, clean it up in Audacity and then repatriate it back to the video. Video is in .mp4 format.

since i upgrade my pc to 10.04 lucid i cannot get any audio when i play videos on the web. i can have tried videos, comcast, hulu, etc... the video plays just fine, but no audio. i can go to apple.com and play videos just fine with audio. i can play any other audio just fine (mp3's, cd's, etc...). so i have narrowed it down to possibly a flash player issue. i have tried flashplayer-nonfree, flashplugin, etc... and no luck. here is where it gets weird. i saw a similar post and they tried creating a new account and it worked. so i tried that. i created a test account and all of the videos play just fine without any issue.
does anyone know if there is a way to rebuild or repair an account in ubuntu? i have checked all of the group memberships and they all match the new account that i setup.

My work just installed a new surveillance system and it uses .box video files and .idx audio to go along with it. They have a windows program to view them but I would love to keep on using my Ubuntu laptop.

For some reason, I cannot record video with cheese. I cannot record video and audio on ....., just video. I can record audio on sound recorder. Why can't I get both? I have an e-machines (acer)em-250, 2g ram, 2ghz intel atom processor. Using Moon Os 4 neak (ubuntu 10.10 variant). I have downloaded and installed ffmpeg, and all other codecs. I can also get video on google voice and video, but no audio. Obviously I have a built-in webcam and mic. I've had this problem with every ubuntu distro I've tried since Oct. of 2010. This netbook came with Win. xp, and I had no problems with this issue then. I would just REALLY like to be able to use my webcam and be able to record video and audio.

i don't know if this is an ubuntu problem or kde problem, but... yesterday, i put my computer into hibernation with a few programs open...one of them was vlc; i had a video paused when i went into hibernation. when i booted back into it, my audio wasn't working for anything... system sounds, programs, flash video online, etc. i went into the sound options and noticed that the 'test' button was giving me sound for hda intel (alc268 analog) but not for pulse audio...well, for a while now, my programs tells me 'hda intel not working, falling back on pulse audio' or some such thing...which is why it's so odd that hda intel is working when i click 'test' in the options but pulse isn't. but it still falls back on pulse for every program, and since pulse isn't giving me any sound......
i'm not getting audio and i don't know how to fix it. hda intel hasn't been working properly for a while, but again, falling back on pulse still worked so i was always too lazy to learn how to fix that. oddly enough, i did manage to get it working again with amarok...at first nothing was outputting sound, but now amarok is working again. but that's it - nothing in vlc, videos isn't making sound, no pidgin im noises, no startup and shutdown sounds, nothing. it's very baffling. all i know is that when i booted back in from hibernation, my volume controls were muted and my internet wouldn't let me connect and said 'networking disabled'. i had to restart to get that working again and i thought nothing of it until i noticed i had no audio.

I seem to be having some audio clashes. I use Exaile to play music (if that matters), and after I play music, no sound comes out of videos (not just Ubuntu, it won't work from Yahoo or MSN videos either). Then when I try to go back to playing my music on Exaile, no sound will come out of that. Likewise, if I restart the computer... the sound works again. If I instead watch a video first, there will be sound -- but as soon as I try to play music from Exaile, nothing comes out.

I'm using a PS3 Eye, which seems to work out of the box on my Ubuntu 9.10 system (both Skype, and Cheese). When I have a pidgin chat window open for one of my contacts, in the media options (under Conversation) the audio, video, and audio/video option is ghosted out (non selectable).
I have the Video plugin checked (ticked), with the input video selected (the cam shows up in the list, and it's selected): for the Eye, I select for both the Audio and Video device. But when I close the plugin configuration window, it defaults back to "Default" which i'm guessing is part of the problem.The audio and video options in pidgin is relative to my system correct? So even if the other user doesn't have that capability, it'll still let me use audio/video for them?

I'm not sure what's causing it, but when I play or pause a flash video in Firefox or Chromium, there's about a second of audio delay.

I'm trying to extract the audio from an mp4 video file and convert it to mp3 using ffmpeg. The problem is that the resulting audio file is only 3m2s long, whereas the video file is 8m15s long. Anyone know why the audio file is being truncated? Am I doing something wrong? Apart from being truncated the mp3 file plays perfectly. Here's what ffmpeg has to say about the video file:
Code:
Seems stream 1 codec frame rate differs from container frame rate: 59.83 (59834/1000) -> 29.92 (359/12)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Part1.mp4':
Duration: 00:08:15.60, start: 0.000000, bitrate: 541 kb/s
Stream #0.0(und): Audio: aac, 44100 Hz, stereo, s16
Stream #0.1(und): Video: h264, yuv420p, 1152x720, 29.92 tbr, 29.92 tbn, 59.83 tbc
And here's the command I'm using to extract and convert the audio:
Code:
ffmpeg -i Part1.mp4 -ab 128k Part1.mp3

I want to do a screen capture with audio and video. I use Ubuntu 10.04 64-bit.I have now spend about half a day trying various tools, most of which seem to be half finished or abandoned. I have not found any usable docs for any of these.gtk-recordmydesktop and xvidcap will both capture video, but seem unable to capture audio from a microphone. The mic is connected and the sound preferences "input" tab shows the input level jumping up when I speak, so it must be working.
I tried the pulse audio device chooser app to make sure the mic is selected, but the choices for input are DEFAULT and "other", which shows a blank input with no choices.xvidcap multi-frame dialog has dev/dsp pre-selected as the input device, with no other options. It does not work.If I enable audio with gtk-recordmydesktop, it refuses to start and says it cannot open the sound card. There is no apparently no way to do this using the "advanced" dialog which has DEFAULT preselected as the audio input device and no other options. /dev/dsp also fails to start.I spent some time searching google and the forums here, to no avail. So should I give up trying to do this with Linux or is there some obscure method I only need to discover?I prefer xvidcap, since the ogg format output by recordmydesktop seems to be a write-only format.
